hi... now that the backend is mostly done, i am thinking about a GUI for netjack. i already found gtknetsource.py on my HD, i started mucking with that some months ago. i plan to extend that thingy now. but setting up the connection, and getting IP addresses of users is still a PITA. i am thinking along the lines of an IM like thing, based on jabber. i am not seeing good options to making this available in the various IM clients. thats why i would rather like to have modified jabberd running on jackaudio.org or at the consortium servers. it would not support chatting or stuff. only show who is online. and if a session is running. it would only make the IP of a user available when he agrees, to open session... blabla... security. so basically you click on your buddy, to open a session. buddy agrees. IP of buddy is transmitted. tool measures connection. provides you with some options. ie compression ratio, number of channels, latency, who is master ? and starts the netjack session. thoughts ? -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

[LAD] [ANN] zynjacku version 2 released

by Nedko Arnaudov

In this release: * zynjacku codebase updated to the latest state of LV2 art. Especially, event MIDI port synths are now supported. * The tarball now contains lv2rack - a host for LV2 effect plugins. * Saving/restoring of presets. Does not work for dynparam plugins yet. * LASH support (autodetected at runtime). * Lot of general fixes that should make zynjacku more usable. I would like to thank Krzysztof Foltman for adding support for some LV2 extensions and Martin Raspaud for helping with slv2 compatibility during my LADI quest. zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK MIDI input port (routed to all hosted synths) and one (two for stereo synths) JACK audio output port per plugin. Such design provides multi-timbral sound by running several synth plugins. zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid parts for synthesis itself and you have flexible part that allows synthesis to suit your needs. lv2rack is a host for LV2 effect plugins. You need slv2 library, Pyhton bindings for PATH and lv2dynparam host library to compile zynjacku tarball.

[LAD] ASUS mobo NEW thread - started OT for another tread

I got another reply off-list about the MIDI issue. Here it is, including my answer: Subject: Re: [LAD] Audio vs ASUS mobo - MIDI Date: Sat, 29 Nov 2008 14:34:42 +0100 From: Ralf Mardorf To: References: wrote: > On Sat, 2008-11-29 at 08:32 +0100, Ralf Mardorf wrote: > > >> If I try to use MIDI applications like Rosegarden, Qtractor and soft >> synth like Qsynth (using an USB MIDI IO device and a Envy24 based sound >> card) I only get crashes. >> > > I got that on kernel 2.6.26-rt when I upgraded from 2.6.24.

I tested Suse 11.0 with the distro's real-time kernels, not with the Jengelh once. Suse 11.0 at the moment is 2.6.25 and I tested 64 Studio 2.1 with the default real-time kernel 2.6.21 and a self compiled real-time kernel 2.6.24. I know that the ASUS M2N-SLI Delux has another chipset than my ASUS M2A-VM HDMI, but because both mobos are relatively new, there might be something in common. MIDI applications crashes without any useful messages for my ASUS M2A-VM HDMI with an AMD BE-2350 CPU using Suse 11.0, 64 Studio 2.1 default (Etch) and 64 Studio 2.1 upgraded to Lenny. Another user has a Gigabyte ga-p35-ds3l with an Intel q6600 CPU and the same problems, he now runs Windows for MIDI work, but started with 64 Studio, Arch and Sidux, he also tested different kernels. His mobo is fine with XP, Cubase SX and Halion, 100% stable. I don't have any Windows install for my computer, so I don't have any information about this. For my mobo Linux is stable for any thing else, but MIDI applications, resp. when I try to run MIDI applications, often their audio clients, resp. JACK fails. I still hope it will be possible to solve the problem. I have the latest BIOS version for my mobo. Until now I only tested 64-bit distros and never a 32-bit version. What mobo, CPU and distro do you use? Thanks, Ralf

The first device above I have not been able to get a peep out of, so I've made the second one, the Audigy2, the default. And I have NDI where to plug anything that looks like audio into that ATI based HD-2400-Pro video card, but lspci says its there. Testing the sound for the audigy2 in system-config-soundcard works, but places like utube are silent. As is cnn et all since the last reboot. 2 questions: do we have a 'vu meter' that can be switched to monitor the various audio inputs? And when I had to reinstall, I see that pulseaudio was installed, and a now frozen 'lsof|grep audio' returns this, but has not returned a prompt. [root@coyote cards]# lsof |grep audio pulseaudi 3473 root txt REG 8,3 57972 53801556 /usr/bin/pulseaudio artsd 3528 root mem REG 8,3 96380 53795593 /usr/lib/libaudio.so.2.4 artsd 3528 root mem REG 8,3 171580 5603705 /usr/lib/libaudiofile.so.0.0.2 Is this yet another case where I need to remove as much PA as I can in order to get working sound again, or is there a configurator for this PITA that might be able to fix this? The silence here is deafening. Thanks. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

[LAD] ANN: buzztard 0.4.0 "the light in your eyes"

by Stefan Kost

hi, The buzztard team has released version 0.4.0 "the light in your eyes" of its buzz-alike music composer. All modules got extensive improvements over the last release from a half year ago. It is usable now and fun to play with. Give it a try and report bugs. bml -------------------------------------------------------------------------------- Major addition is wavetable support for tracker plugins. Besides that the new release improves buzzmachine compatibility, performance and has a better build setup. bsl -------------------------------------------------------------------------------- Major addition is wavetable support. Several bug fixes and build system cleanups. buzztard -------------------------------------------------------------------------------- As planned, main focus for this release was the wavetable support. Its done - buzztard can load what gstreamer can decode. The wavetable view has a nice waveform widget. Related to that buzztard has a new song-format that bundles the XML together with external files in a zip archive. Also the UI has seen a lot of improvements. The machine view looks nicer - Marc drew spiffy machine icons. In addition they now show real volume meters when playing. All meters are now properly synced. gst-buzztard -------------------------------------------------------------------------------- API renaming to cleanup gst namespace usage. Now includes former gstbml module. project-page: http://www.buzztard.org screenshots: http://www.buzztard.org/index.php/Screenshots downloads : http://sourceforge.net/project/showfiles.php?group_id=55124 buzztard core developer team -- http://www.buzztard.org

[LAD] musicxml question

by Nathanael Anderson

I'm considering using music xml for a project i'm working on, does anyone here know how useful it is for guitar tab, where the same note can be played in multiple places on the fretboard, but postioning is important so the player doesn't have to move too far on the kneck. Thanks for any feedback, Nathanael

[LAD] Jack MTC/MMC slaving

by Alex Montgomery

Hello, I'm guessing from the research I've done online and from the lack of responses to my LAU message ( http://www.nabble.com/Slaving-jack-to-MMC-MTC-to20357929.html ) that JACK does not currently support slaving to external (or internal?) devices via MMC/MTC. I'm a C/C++ developer by trade, so I'm happy to get my hands dirty, but I wanted to know what other work, if any, has been done on this front. I've been told that both Rosegarden and Ardour can sync to MTC, but that they cannot then drive JACK transport in that mode. Would it be difficult to move this code over to JACK? Is there a reason this in't desirable? There's a small program called jackctlmmc that seems to do want I want, but it's a bit limited (seems pretty hardcoded) and I think that such a desirable feature should be integrated into a more widely used program. Any thoughts? Thanks, -- Alex

[LAD] problem with scheduling alsa events

by nescivi

Hiho, In the Midi output code of this opensource project I am working on, there is a problem with the timing when alsa events are scheduled in the future. The events take much longer to arrive (sometimes almost minutes later!). Below is the code snippet. Can anyone see what is wrong in here? Let me know if you need more code... sincerely, Marije int SC_AlsaMidiClient::sendEvent(int outputIndex, int uid, snd_seq_event_t* evt, float late) { snd_seq_real_time time; if ((outputIndex < 0) || (outputIndex >= mNumOutPorts)) return errIndexOutOfRange; snd_seq_ev_set_source(evt, mOutPorts[outputIndex]); if (uid == 0) { // send to all subscribed ports snd_seq_ev_set_subs(evt); } else { // send to specific port int cid, pid; SC_AlsaParseUID(uid, cid, pid); snd_seq_ev_set_dest(evt, cid, pid); } // late is the latency value in seconds in floats if (late > 0.f) { // old time calculation: // time.tv_sec = (unsigned)(late * 1.0e-6f); // time.tv_nsec = (unsigned)(late * 1.0e3f); // new time calculation. The old one was not correct time.tv_sec = (unsigned)(late); // seconds time.tv_nsec = (unsigned)(late * 1.0e9f) % 1000000000; // nanoseconds // should these be (long) instead??? } else { time.tv_sec = time.tv_nsec = 0; } post("MIDI (ALSA): sending event, time %i, %i, late %f\n", time.tv_sec, time.tv_nsec, late); snd_seq_ev_schedule_real(evt, mQueue, 1, &time); snd_seq_event_output_direct(mHandle, evt); return errNone; }

[LAD] jackctlmmc (kinda sorta) release

by Alex Montgomery

Hello, We'd like to announce a new release of jackctlmmc, a command line tool for driving JACK transport using Midi Machine Code that you can download here: https://sourceforge.net/project/showfiles.php?group_id=245788 or get the code here: http://repo.or.cz/w/jackctlmmc.git The program is still in its infancy but it should work for most MMC devices. It currently supports the following MMC commands: Play / Deferred Play - start transport Stop - stop transport Rewind - go to time 0 Goto: go to the specified SMPTE time It's a pretty simple command line utility for now, but we'll be working on a QT front end soon. To use jackctlmmc: 1) start the program on the command line: ./jackctlmmc -f <your device's SMPTE frame rate> -t <jitter tolerance in milliseconds> You can also specify -v if you want it to output messages in the console for all MMC commands it's handling, which is useful for testing. 2) connect your midi port to jackctlmmc using either aconnect or JACK's connect (you will have to specify JACK's midi driver as "seq" if you want to connect using JACK). For the goto command to work, jackctlmmc needs to know your device frame rate which you can specify with -f, or use the default 30 fps. Some MMC devices (like my BR900CD 8-track) are awfully spammy with their goto messages, so we've implemented a jitter tolerance (specified in milliseconds on the command line with -t, defaulting to 50) so jackctlmmc will ignore goto commands that are already close enough to the current JACK transport time. There's still a lot of work to do on the application, but we've been getting emails asking for progress updates, so we decided to do a quick release now. Hopefully it's useful to people other than ourselves. -- Alex
